Hi Kiruba,
From the error: VerifyError: Error #1053: Illegal override of z in FreeSpin3D.ZZ2733.
I can learn that you try to load player 10 version of Freespin3D to a swf in player 9 version.
Note that FreeSpin3d is derived (extend) from Sprite. In Player 10 version it override the z member and in Player 9 the Sprite don't have z member.
So use FLEX SDK 3.4 or later and set it to player 10 version.
I hope it will solve the problem.
Come through... you might like it !!!
